Shockwave vs. Cortisone: Two Very Different Approaches to Tendon Pain

Shockwave vs. Cortisone: What’s the Difference?

When pain starts limiting workouts, sports, walking, golf, or even sleep, many people are offered a cortisone injection as an early treatment option.

Sometimes that makes sense.

Cortisone can reduce pain relatively quickly, especially when inflammation is highly involved. But many chronic tendon problems are more complex than simple inflammation alone.

That distinction matters.

At SB Physio, we commonly use radial pressure wave therapy, often referred to as radial shockwave therapy, as part of a broader rehab approach for chronic tendon and soft tissue conditions.

The goal is different from simply numbing pain.

What Is Cortisone?

Cortisone is a corticosteroid medication typically injected into painful tissue or joints to decrease inflammation and reduce pain.

It is commonly used for:

• Shoulder pain

• Bursitis

• Plantar fasciitis

• Tennis elbow

• Joint irritation

• Tendon-related pain

In many cases, cortisone can help calm symptoms quickly.

But for chronic tendon problems, short-term pain reduction does not necessarily mean the tendon itself has improved.

Research has shown corticosteroids may negatively affect tendon collagen structure and tendon cell activity, particularly with repeated exposure.

That is one reason many providers are cautious with repeated injections around structures like the Achilles tendon.

What Is Radial Shockwave Therapy?

Radial shockwave therapy, more accurately called radial pressure wave therapy, uses mechanical pressure waves applied through the skin into painful tissue.

It is different from focused shockwave therapy.

Focused shockwave delivers energy deeper and more precisely, while radial pressure wave therapy disperses energy more broadly and superficially.

Radial shockwave is commonly used for:

• Plantar fasciitis

• Achilles tendinopathy

• Tennis elbow

• Patellar tendinopathy

• Gluteal tendinopathy

• Chronic soft tissue pain

Current evidence suggests shockwave therapy may help reduce pain and improve function in several chronic tendinopathies.

Importantly, shockwave is usually not viewed as a standalone cure. It is often paired with:

• Progressive strengthening

• Tendon loading programs

• Mobility work

• Activity modification

• Return-to-sport progression

The Main Difference: Suppression vs. Stimulation

A simplified way to think about the two approaches:

CortisoneRadial ShockwavePrimarily attempts to suppress inflammation and painAttempts to stimulate a tissue responseOften faster short-term pain reliefUsually more gradual improvementInjection-basedNon-invasiveMay be useful for acute irritationOften used in chronic tendon conditionsRepeated exposure may negatively affect tendon tissueCommonly paired with strengthening and rehab

Neither treatment is universally “better.”

The more important question is:
What type of tissue problem are we actually dealing with?

Why Chronic Tendon Pain Is Different

Many chronic tendon conditions are now understood to involve tissue degeneration and altered tendon structure rather than ongoing classic inflammation alone.

Over time, tendons can become:

• Less tolerant to load

• Thickened

• Disorganized

• Pain-sensitive

That is why simply resting or suppressing symptoms does not always solve the problem long term.

Modern tendon rehab typically focuses on improving:

• Strength

• Load tolerance

• Tissue capacity

• Movement quality

Shockwave is often used alongside this process rather than replacing it.

Does Radial Shockwave Hurt?

Sometimes.

Most patients describe it as uncomfortable but tolerable. Treatment intensity can typically be adjusted based on the body region and irritability level.

Sessions are usually brief and performed over multiple visits.

Unlike cortisone injections, radial shockwave does not involve needles or medication.

Is One Better?

It depends on:

• The diagnosis

• Duration of symptoms

• Irritability level

• Tissue involved

• Activity goals

• Previous treatment history

A cortisone injection may make sense in certain situations where reducing inflammation quickly is the priority.

Radial shockwave may make more sense when chronic tendon pain, loading intolerance, and tissue quality are part of the bigger picture.

Neither replaces a full evaluation and progressive rehab plan.

How We Use Radial Shockwave at SB Physio

At SB Physio, radial shockwave is typically integrated into a larger physical therapy strategy rather than used as an isolated treatment.

Depending on the condition, treatment may also include:

• Strength progression

• Mobility work

• Force and movement analysis

• Return-to-sport planning

• Recovery strategies

• Load management education

The goal is not simply temporary pain reduction.

The goal is improving movement, function, and long-term tissue tolerance.
